The present disclosure provides for aqueous, curable binder compositions, as well as articles and products comprising assemblies of matter comprising mineral fibers, synthetic fibers, natural fibers, cellulosic particles and sheet materials comprising the binder compositions disclosed herein.

Textile compositions comprising at least one filamentous fungus are disclosed, as are methods for making and using such textile compositions. Embodiments of the textile compositions generally include at least one of a plasticizer, a polymer, and a crosslinker, in addition to the filamentous fungus. The disclosed textile compositions are particularly useful as analogs or substitutes for conventional textile compositions, including but not limited to leather.

Cellulose fibers are impregnated with polyethyleneimine so that the impregnation forms a type of network, which can reduce the specific resistance of the cellulose material owing to the electrical conductivity of the network. The cellulose material can thereby be advantageously adapted to use as electrical insulation of transformers, the cellulose material in this case being soaked in transformer oil. An adaptation of the specific resistance of the cellulose material to the specific resistance of the oil lead to improved dielectric strength of the transformer insulation. A method for impregnation of the cellulose material is described.

The invention pertains to a layered high-void-fraction material comprising a composite surface layer comprising structural material and a polyester derived from an aliphatic polyol with 2-15 carbon atoms and an aliphatic polycarboxylic acid with 3 to 15 carbon atoms, wherein the surface layer is connected to a high-void-fraction layer of structural material. As compared to a high-void-fraction material without the composite surface layer, the material has, among others, improved surface properties, and improved bending stiffness, while insolation properties for both sound and heat are maintained. The material may be used, e.g., as insulating material, as filtration material, or in hydroponics.

A fiber-dispersed resin composite material, containing fiber dispersed in a resin, wherein the content of the fiber in the fiber-dispersed resin composite material is 1 mass % or more and less than 70 mass %, and wherein the fiber-dispersed resin composite material has a maximum color difference A determined under conditions below of 0.05 or more and 6 or less:

<Conditions>

L*, a*, and b* values in CIE (L*a*b*) color space are measured on a straight line at 8 points with an interval of 1 cm by using a chromameter, and a color difference ΔE1 between measurement points linearly adjacent to each other is calculated by [Expression 1-1] below while a maximum value among 7 calculated values for the resulting color difference ΔE1 is set as the maximum color difference A,

[00001]$\begin{array}{cc}\Delta E1={\left[{\left(L_{i+1}^{\star }-L_i^{\star }\right)}^2+{\left(a_{i+1}^{*}-a_i^{*}\right)}^2+{\left(b_{i+1}^{\star }-b_i^{\star }\right)}^2\right]}^{0.5}& \left[\mathrm{Expression}1\text{-}1\right]\end{array}$ where L*.sub.i, a*.sub.i, and b*.sub.i are the L*, a*, and b* values at i-th measurement point among the 8 measurement points, and i is an integer of 1 to 7 in [Expression 1-1].

Textile compositions comprising at least one filamentous fungus are disclosed, as are methods for making and using such textile compositions. Embodiments of the textile compositions generally include at least one of a plasticizer, a polymer, and a crosslinker, in addition to the filamentous fungus.

The invention relates to a process for manufacturing a nonflat article comprising the steps of providing a structure comprising a fibrous material and a resin comprising a polymer derived from an aliphatic polyalcohol with 2-15 carbon atoms and an aliphatic polycarboxylic acid that has an extent of polymerization of above 0 to 1.0, or the precursor monomers of such polymer, wherein the structure has a void fraction of 0.3-0.98 and a water content of below 40 wt. %; and subjecting the structure to the following steps polymerising to an extent of polymerisation of 0.5-1, if necessary, pressing to reduce void fraction, and forming the structure into a non-flat article by applying a force at an internal temperature above glass transition temperature (T.sub.g) of the polymer in a defined order to form a non-flat article having an extent of polymerisation of at least 0.5 and a water content less than 20 wt. %. The invention also relates to non-flat articles obtainable by the process and structures suitable for use in the process.

A thermoplastic prepreg includes a mat, web, or fabric of fibers and hollow glass microspheres that are positioned atop the mat, web, or fabric of fibers or dispersed therein. The thermoplastic prepreg also includes a thermoplastic polymer that is fully impregnated through the mat, web, or fabric of fibers and the hollow glass microspheres so that the thermoplastic prepreg has a void content of less than 3% by volume of the thermoplastic prepreg. The thermoplastic material is polymerized monomers and oligomers in which greater than 90% by weight of the monomers or oligomers react to form the thermoplastic material.

The invention relates to a multilayer prepreg comprising a first and a second fiber prepreg, one or two micaceous prepregs and B staged thermosetting resin, which may be different for each layer or identical. The micaceous prepregs are positioned on the top (outside) of the fiber prepregs. There may be plurality of further fiber prepregs. The micaceous prepregs preferably comprise mica flakes in the form of a mica paper. The use of such prepreg as surfacing layer at the top of a composite material or near the top of a composite material can determine an improvement in burn-through and fire retardancy performance of composite materials. It is also disclosed a cured composite panel, such as an aircraft part, obtainable by curing the multilayer prepreg to a C stage.
