Fibrids comprising poly alpha-1,3-glucan or surface-modified poly alpha-1,3-glucan were produced and characterized. Applications and products for using these fibrids were also developed, such as in emulsification, viscosity modification, and paper. Examples of surface-modified poly alpha-1,3-glucan fibrids include those with a positive surface charge.

Prepregs, composites and articles are described that comprise a porous core layer and a surface layer comprising bi-component fibers which can enhance formability of the article without breakthrough. The enhanced formability can permit forming or drawing of the article to increased depths without breakthrough. Interior and exterior automotive components including the articles are described.

A flame-blocking nonwoven fabric has excellent processability and high flame-blocking properties. The flame-blocking nonwoven fabric has a density of 200 kg/m.sup.3 or more and includes non-melting fibers A whose high-temperature shrinkage rate is 3% or less and whose Young's modulus multiplied by the cross-sectional area of the fibers is 2.0 N or less, and thermoplastic fibers B whose LOI value is 25 or more as determined according to JIS K 7201-2 (2007).

Certain configurations are described herein of a thermoplastic sheet or article comprising a plurality of porous layers coupled to each other. In one configuration, the thermoplastic article may comprise a core layer, a first layer disposed on one surface of the core layer and a second layer disposed on another surface of the core layer. In some instances, each of the core layer, the first layer and the second layer may comprises a web of open celled structures formed by a plurality of reinforcing materials bonded together with a thermoplastic material and optionally may also include a lofting agent. The lofting capacity in different layers can be selected or tuned to provide desired properties.
