The tape is woven to form a textile, which is layered and heat-bonded to create the self-reinforced composite material. The sheet offers stiffness, strength, and impact resistance about five times that of non-reinforced polypropylene.

Self-reinforced composite (SRC) has gained significant interest due to its lightweight and good recyclability. In the present work, SRCs were prepared from woven polypropylene tapes. The woven tapes were further stitched by lock stitch and its effects on flexural and impact properties of the composites were studied.
Characteristics of Self-Reinforced Plastic The formation process for self-reinforced plastics results in a lightweight, strong composite. Because other materials, such as glass, aren’t used, the end product is easier to recycle without compromising its strength.
Comfil develops and produces thermoplastic composites based on commingled yarns. Carbon, glass etc combined with thermoplastic filaments in one yarn
Curv is an outstanding material that combines the versatility of a 100% thermoplastic with the high performance of a fiber reinforced composite. Curv captures the advanced mechanical properties of highly oriented polypropylene tapes in a self-reinforced polypropylene matrix.
The world of composites is young, dynamic and quickly growing into a vast range of segments, markets, applications and technologies. To learn more about it, JEC Group proposes a wide range of publications that will allow you to learn all about the trends and forecasts of the composites industry, and about the key players from the sector.

Highly oriented polypropylene fiber reinforced random PP copolymer composites were produced by film-stacking method. The reinforcing fibers were carded and needle punched and the film-stacked packages were compression molded at different processing temperatures (T=150…170°C) and holding times (t=90…600 s).
Carbon/PP and carbon/self-reinforced PP hybrid composites have been produced by film-stacking. Tensile tests in carbon/PP composites show that the E-modulus is 15% lower than expected.
the self reinforced polymer composites offer significantly higher properties than the virgin polymers from which they are made; for example Cabrera shows that at room temperature the all-polypropylene material Pure displays a Young’s modulus of 5.9GPa .
Self-reinforced polypropylene composites (SRPPC) were manufactured with film stacking method at different processing temperatures (T=150-175°C) at a constant pressure of 5·5 MPa and holding time of 90 s with a nominal reinforcement content of 50 wt-%.
of self-reinforced polypropylene (SRPP) depend on process parameters such as temperature, pressure and dwell time, and on material specific parameters such as weave architecture and tape draw ratio [13, 14].
Flame retarded self-reinforced polypropylene composites were manufactured by injection moulding method for the first time. By this means, besides the conventional processing methods resulting in 2-dimensional SRPC sheets, the production of three-dimensional products becomes also realizable.
1. Introduction The negative environmental impact of the steadily increasing use of plastic and composite materials requires the development of new combinations of
Self-Reinforced Polymers (SRPs) Self-reinforced polymers (SRPs) are a particular family of thermoplastic composite materials in which both the reinforcing fibre and the polymer matrix are from the same polymer family (for example, polypropylene-reinforced polypropylene).
self-reinforced composites Recyclability is a primary — but not the only — driver in the development of self-reinforced plastics (SRPs). The following three SRP sheet materials were developed initially for automotive applications, but also are proving useful in industrial, sporting goods and consumer goods applications.
A systematic investigation was carried out to determine the optimum consolidation process conditions of a co-extruded polypropylene self-reinforced composite (SRC) considering its structural characteristics and static and time-dependent deformation behavior.
2 Low density of the all-PP composite translates to weight savings at the same part thickness relative to glass/ PP composites. Desirable stress-strain properties result in good impact strength. The self-reinforced composite possesses a unique combination of high strain-to-failure
An interesting take on fibre reinforced materials, this polypropylene sheet is reinforced with a lattice structure made from polypropylene. The sheets are stiffer and stronger than regualr polypropylene while retaining a waxy and mostly smooth texture.
